Vitamin A

Vitamin A is a fat soluble vitamin - also labeled as Retinol - that is also a powerful antioxidant. Vitamin A plays a critical role in maintaining healthy vision, neurological function and healthy skin. It is involved in reducing inflammation through fighting free radical damage. It naturally slows aging. Antioxidants like Vitamin A are also responsible for building strong bones, regulating gene regulation, maintaining healthy clear skin, facilitating cell differentiation, and supporting immune function. The U.S. recommended dietary allowance (RDA) for adults is 900 micrograms daily (3,000 IU) for men and 700 micrograms daily (2,300 IU) for women. Pregnant women that are 19 years old and older should have 770 micrograms daily (2,600 IU); and lactating women above 19 years old are advised to take 1,300 micrograms daily (4,300 IU). Vitamin A deficiency can cause poor eye health, premature skin damage, respiratory infections and at risk pregnancy. High doses of vitamin A may actually do more harm than good. Over-consumption of vitamin A can lead to jaundice, nausea, loss of appetite, irritability, vomiting, and even hair loss. Symptoms of vitamin A toxicity include dry skin, joint pain, vomiting, headaches, and confusion.
